Abstract

The utility model relates to a coping saw whose upper and lower suspension arms, connecting rod 1 and saw blade form a parallel four-bar linkage mechanism. Thus the rotary motion of a motor is converted into upward and downward swing of the suspension arms, causing the suspension arms to drive the saw blade to do reciprocating motion to achieve the purpose of workpiece cutting. The utility model has the advantages of high efficiency, rapidness, time saving, labour saving, accuracy, simple structure and reliable operation, and is particularly suitable for use in household and decorative upholstery.

Description

A kind of sweep-saw

The utility model relates to a kind of sweep-saw

At present, during the sawing woodwork, all need manual finishing in family or the decoration industry, not only time-consuming, but also effort, and industrial electric saw is not suitable for family or decoration is already used, and therefore, people wish to have a kind of can replace manual operations, safety, accurately, sweep-saw occurs easily.

The purpose of this utility model is at the prior art above shortcomings, a kind of sweep-saw is provided, this sweep-saw not only can replace the manual operations during the sawing woodwork in family and the decoration industry fully, and safe, accurate, convenient, fast, can also cut light non-ferrous metals such as aluminium.

The purpose of this utility model is achieved in that a kind of sweep-saw, by support, fuselage, adjustable supporting plate, motor, on, lower cantalever, link rod I, link rod II, clamper, bent axle and switch module constitute, it is characterized in that, lower cantalever is contained in the fuselage with axle, the two ends of link rod I connect respectively, one end of lower cantalever, the other end of upper cantilever is installed clamper, the other end of lower cantalever is installed lower gripper, saw blade is promptly used, lower gripper is fixed on, on the lower cantalever, on, lower cantalever, link rod I and saw blade form parallel four-bar linkage, motor shaft extension end is installed bent axle, link rod II connects bent axle and lower cantalever, with this rotatablely moving of motor transformed into swinging up and down of cantilever, it is reciprocating to make cantilever drive saw blade, cut workpiece, and the supporting plate of supporting workpiece is fixed by bolts on the support, the supporting plate bottom is equipped with adjustable handle, makes supporting plate can be fixed on any position of 0～45 °.

The utility model compared with prior art has the following advantages: 1. because the utility model is mechanized operation, therefore efficient, quick, time saving and energy saving; 2. because the motion formed by bent axle, link rod and cantilever is newly moulded in this practicality rotatablely moving of motor become the reciprocating motion of saw blade, realize the purpose of cut workpiece, therefore simple in structure, running is reliable; 3. the utility model processing ease is fit to family and decoration and already uses very much.

Below in conjunction with accompanying drawing, the utility model is described in detail in detail with specific embodiment of the utility model.

Fig. 1 is a perspective view of the present utility model;

Fig. 2 attempts for master of the present utility model looks cross-section structure;

Fig. 3 is A-A cross-sectional view of Fig. 2;

Fig. 4 is a right TV structure schematic diagram of the present utility model.

As Fig. 1; 2; 3; shown in 4; motor is contained on the support 10; fuselage 11 also is fixed on the support 10; on; lower cantalever 2; 9 use axle 19 respectively; 20 are installed in 11 li on fuselage; the two ends of link rod I are respectively with last; lower cantalever 2; an end of 9 links to each other; last clamper 5 is installed in the other end of upper cantilever 2; lower gripper 8 is installed in the other end of lower cantalever 9; saw blade 6 is by last; lower gripper 5; 8 are fixed on; lower cantalever 2; on 9; make; lower cantalever 2; 9; link rod I and saw blade 6 form parallel four-bar linkage; the shaft extension end of motor shaft 21 is installed bent axle 12; link rod II13 connects bent axle 12 and lower cantalever 9; make rotatablely moving of motor be converted into swinging up and down of cantilever; cantilever 2; 9 drive saw blade 6 moves back and forth; reach the purpose of cut workpiece; with supporting plate 7 usefulness bolts 22; 23 are fixed on the support 10; the bottom of supporting plate 7 is installed and is adjusted handle 24; be used for regulating the angle of supporting plate 7; make supporting plate 7 can be fixed on 0～45 ° optional position; therefore the utility model can cut the workpiece of various angles; workpiece is beated with saw blade 6 when preventing work; cantilever guard shield 14 near on the end of clamper 5 a spring installing rack 25 is installed; spring pressuring plate 16 is installed on the cross bar of this mounting bracket bottom; in order to prevent operating personnel's hand contact saw blade; one fender bracket 26 is installed on mounting bracket 25 again; the sawdust that produces in order in time to work sweep-saw the time blows away; make operating personnel can more clearly see the line of surface of the work; one air bag 3 is installed between upper cantilever 2 and cantilever guard shield 14; when sweep-saw is worked; upper cantilever 2 and cantilever guard shield 14 extruding gasbags 3; make its exhaust, just can belong to the saw of surface of the work and blowing away.

But clamper 5,8 select tape pins of the present utility model and the different multiple saw blade machining of width, can realize the cutting of two different directions in front or side, can reach the purpose of adjusting saw blade by knob 4, convenient, rapidly, and can adapt to the requirement of various different size workpiece.17 is power switch among Fig. 1, and 18 is speed switch.

During use, thickness according to institute's processing work, character such as hardness and length is selected the suitable saw blade and the direction of sawing, thickness of workpiece is bigger, hardness is higher, when the Processing Curve radius is big, should select broad, harder saw blade, otherwise, should select narrower saw blade, side cut energy processing length is longer, workpiece that can't the front sawing installs saw blade 6, and adjust its tensity, according to the angle of the angle Selection supporting plate 7 of wanting processing work, and adjust and to fix supporting plate 7, according to the thickness of workpiece, the height of regulating spring compressing tablet 16 makes it that workpiece is fixing well by on the supporting plate 7.
